開発環境が整っている前提で進めていきます。
仕様は次のとおりです。
仕様
- S3上にある非公開の動画を使用
- 指定のコントローラーにアクセスしたらS3から動画を表示する
ヘルパーを作成する
ヘルパーは、こちらのライブラリをベースに、少し手を加えます。
主にconstruct部分。

A laravel package to stream video content. Contribute to rajurayhan/larastreamer development by creating an account on GitHub.
最終的にできたコードはこちらです。
<?php namespace App\Helpers; class VideoStreamer { private $path = ""; private $stream = ""; private $buffer = 102400; private $start = -1; private $end = -1; private $size = 0; private $mime = ""; public function __construct($disk, $path) { $this->stream = $disk->readStream($path); $this->mime = $disk->mimeType($path); $this->filemtime = $disk->lastModified($path); $this->size = $disk->size($path); } /** * * * * Set proper header to serve the video content * */ private function setHeader() { ob_get_clean(); $cType = "Content-Type: ".$this->mime; header($cType); header("Cache-Control: max-age=2592000, public"); header("Expires: ".gmdate('D, d M Y H:i:s', time()+2592000) . ' GMT'); header("Last-Modified: ".gmdate('D, d M Y H:i:s', $this->filemtime) . ' GMT'); $this->start = 0; $this->end = $this->size - 1; header("Accept-Ranges: 0-".$this->end); if (isset($_SERVER['HTTP_RANGE'])) { $c_start = $this->start; $c_end = $this->end; list(, $range) = explode('=', $_SERVER['HTTP_RANGE'], 2); if (strpos($range, ',') !== false) { header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $this->start-$this->end/$this->size"); exit; } if ($range == '-') { $c_start = $this->size - substr($range, 1); } else { $range = explode('-', $range); $c_start = $range[0]; $c_end = (isset($range[1]) && is_numeric($range[1])) ? $range[1] : $c_end; } $c_end = ($c_end > $this->end) ? $this->end : $c_end; if ($c_start > $c_end || $c_start > $this->size - 1 || $c_end >= $this->size) { header('HTTP/1.1 416 Requested Range Not Satisfiable'); header("Content-Range: bytes $this->start-$this->end/$this->size"); exit; } $this->start = $c_start; $this->end = $c_end; $length = $this->end - $this->start + 1; fseek($this->stream, $this->start); header('HTTP/1.1 206 Partial Content'); header("Content-Length: ".$length); header("Content-Range: bytes $this->start-$this->end/".$this->size); } else { header("Content-Length: ".$this->size); } } /** * * close curretly opened stream * */ private function end() { fclose($this->stream); exit; } /** * * perform the streaming of calculated range * */ private function stream() { $i = $this->start; set_time_limit(0); while (!feof($this->stream) && $i <= $this->end) { $bytesToRead = $this->buffer; if (($i+$bytesToRead) > $this->end) { $bytesToRead = $this->end - $i + 1; } $data = fread($this->stream, $bytesToRead); echo $data; flush(); $i += $bytesToRead; } } /** * * Start streaming video content * */ public function start() { $this->setHeader(); $this->stream(); $this->end(); } }
コントローラーでヘルパーを読み込む
use App\Helpers\VideoStreamer;
ヘルパーにS3の接続とファイルパスを渡す
コントローラーで次のメソッドを作成します。
public function streamVideoFile() { $disk = Storage::disk('s3'); $path = 's3上の動画ファイルのパス'; $stream = new VideoStreamer($disk, $path); return response()->stream(function () use ($stream) { $stream->start(); }); }
作成したメソッドにルーティングを設定し、ブラウザからアクセスすると動画が再生できます!
